This invention pertains to improvements tion with the lubrication of kin bolts on the 5 in lubricating apparatus. It'is amon the front axles of automobiles. 'l/ vhen the ere objects of the invention to provideia lubricess of lubricant above the effective top of eating apparatus capable of feeding-lubrithe aperture 8 has-flowed-to the bearing, the

My device is particularly". adapted for use: discharge outletconsiderab y above the botin connection with automobiles ",orother tom thereof, atop presenting'a-surhce slop I mechanisms wherein there is vconsiderable-.i n towardthe center thereo ,"said discharge motion of'the parts to provide for splashing Tori-flee beneath the lowermost ortion ofsaid 4 i I of the lubricant held within the'eup. ,The surfacefand a quick detacha le connection invention is particularly useful vin connector engagement by a pressure lubricating gun Y presenting passages communicating with said reservoir whereby the part to be lubricated may be initially flushed under pressure of the lubricant from said lubricant gun and subsequently, when the part to be lubricated is agitated, may receive lubricant splashed from the lower portion of said cup onto said sloping surface and dripping into said discharge orifice, said discharge orifice adjustable to various positions relative to the converging point of said sloping surfaces.

3. An oil cup presenting a reservoir, a discharge outlet considerably above the bottom thereof, a top presenting a surface sloping toward the center thereof, said discharge orifice beneath the lowermost portion of said surface, and a quick detachable connection for engagement by a pressure lubrieating gun presenting passages communicating with said reservoir whereby the part to be lubricated may be initially flushed under pressure ofthe lubricant from said lubricant gun and subsequently, when the part to be lubricated is agitated, may receive lubricant splashed from the lower portion of said cup onto said sloping surface and dripping into said discharge orifice, said discharge orifice provided. in a part eccentrically inovable relative to said cup and relative to the converging point of said sloping surfaces, whereby the proportion of drops from said converging point entering said orifice and not entering said orifice may be varied.

In testimony whereof, I have signed my name to this specification.
